Laboratory Open Mill Electrical Heating Electric Open Roller Mixer Two Roll Mill

It is designed for mixing, milling and processing small batches of plastics, rubbers and other formulation materials for research & development, quality control, prototyping and laboratory testing.

Three mixed capacity ranges are offered: 0.5–1 kg, 2–3 kg and 5–7 kg. Choose the range that best matches your typical batch/sample size.

Power rating is 2800 W and the unit requires AC 380 V supply with a 15 A circuit. Confirm your facility has the appropriate three-phase supply and circuit protection before installation.

The heating system covers room temperature up to 300 °C with a temperature accuracy of ±3 °C.

Typical warm-up time from room temperature to about 150 °C is approximately 20 minutes (actual time may vary with ambient conditions and load).

Rollers are 3.9 inches in diameter and 13.7 inches in length. Roller hardness is HRC 50–60 for durable performance in mixing operations.

The drum (roller) revolutions ratio is 1 : 1.25.

Overall dimensions are 960 × 550 × 1150 mm (L × W × H) and the unit weight is approximately 380 kg. Ensure your workspace and floor loading can accommodate the machine.

The mill features a user-friendly interface for straightforward operation. Operators should receive training on safe operation, temperature control, and sample handling—either from your lab’s experienced personnel or the supplier/installer.

Follow the user manual and general lab safety practices: wear appropriate PPE (heat-resistant gloves, eye protection), avoid contact with hot surfaces and rotating rollers, provide adequate ventilation, isolate power before maintenance, and confirm electrical supply protections. Check with the supplier for machine-specific safety features (emergency stop, thermal cutouts).

Regularly inspect rollers for wear or damage, keep roller surfaces clean and free of cured material, check electrical connections and cables, monitor heating performance, and replace worn parts as needed. Schedule periodic calibration of the temperature control system and have qualified service personnel perform major maintenance.

Allow the unit and rollers to cool before cleaning. Remove bulk residues mechanically (scraping) and, where appropriate, use manufacturer-recommended solvents or cleaning agents safe for the roller surface. Avoid high-pressure washing and follow all chemical safety guidance. Refer to the manual for specific cleaning procedures.

Common service parts typically include rollers, heating elements, temperature sensors, and electrical components. Contact the supplier or manufacturer to order genuine spare parts and to confirm availability.

It is optimized for laboratory use, R&D and small-batch prototyping or quality control. It can handle small-scale production runs, but it is not intended for large-scale industrial continuous production.

Install on a stable, level surface with sufficient clearance for operation and maintenance. Ensure access to the required AC 380 V three-phase power (15 A) and appropriate circuit protection. Allow for ventilation around the unit, and confirm floor loading capacity for a 380 kg machine. Supplier installation and electrical hookup by qualified personnel is recommended.
